The Alta Series high accuracy, extended range current transformers exceed the IEEE 0.15S accuracy standard. These CTs meet or exceed every 600V metering class CT in the industry with metering class 0.15 from 1% of nominal current through rating factor. The COS-6 is also available in standard accuracy with or without a primary bar.

The core is constructed from wound layers of high accuracy, low loss electrical grade steel. The core is evenly wound with enamel coated copper wire to ensure against potential short circuits. The core and coil assembly is encapsulated in polyurethane specifically engineered for premium dielectric, mechanical and thermal properties for use in both indoor and outdoor applications.

Applications

600V Metering current transformers are used in a wide variety of commercial and industrial applications where revenue class metering is necessary for billing purposes. The COM-6 is specifically engineered for pole-mounted applications and wall-mounted meter cabinets.
